There are going to be more and more supercharged E60 M5 and E63 M6 V10 vehicles on the road now that more affordable supercharger solutions are on the market. Velos Designwerks recently installed an ESS-Tuning VT2-650 supercharger kit which uses a Vortech based unit with self-contained oiling and a water/air aftercooler.

On 93 octane pump gas the supercharged car puts down 562 wheel horsepower in STD correction. In SAE the result is 550 wheel horsepower. Conditions were warm in the 90 degree range. Definitely impressive but it would be great to know at what boost levels this rear wheel horsepower was reached.

Kind of disappointing considering the e92 m3 vt2 puts out the same amount of power, even with the 100hp advantage from stock

I was waiting until someone said this.

Well this is on lower boost. Also, the S85 really could use a bigger blower but packaging constraints are the problem. It's the same thing as an S65 just with more displacement. It really will all things being equal beat it.

The E92 M3 has a couple advantages namely a better factory header design, more space in the engine bay for a larger blower, and a DCT transmission. So, I'm just patiently waiting for blown M5 owners to get cocky so they can be reminded who's boss.

Peak numbers may be nearly identical to the E92 ESS VT2-625s that Jean posted in the past, but man that S85B50 packs a big kick in the pants in the midrange. This thing has definitely got to be a blast to drive.

This car is begging for some freer flowing headers. The OE S85 headers are pretty not optimal by overall design with that cat clogging up exhalation. I imagine a nice boost drop and power increase if they got some sexy squigglies coming out of the head...haha
